Low<i>C4</i>,<i>C4A</i>and<i>C4B</i>gene copy numbers are stronger risk factors for juvenile-onset than for adult-onset systemic lupus erythematosus

Abstract

Low total C4, C4A and C4B GCN were associated with a stronger risk for developing JSLE than aSLE. Additionally, low total C4 and C4A GCN are risk factors for pericarditis in JSLE.
